The force can be determined using the equation F (force) = mass * acceleration. The unit of measurement, N (Newton), is equivalent to kilogram-meter/seconds2.
Thus, F= 1300 kg * 1.07 m/s2 = 1391 N.
The resultant value is 1391 N.
Answer:
h = 10 m
Explanation:
Given,
mass of the platform = 50 Kg
Kinetic energy = 5000 J
height from which the diver dove =?
Taking the acceleration due to gravity as 10 m/s²
Using the conservation of energy principle
Kinetic energy is transformed into potential energy
K.E = P.E
K.E = m g h
5000 = 50 x 10 x h
500 h = 5000
h = 10 m
The height from which the diver dove is equal to h = 10 m
<span>The work done corresponds to the potential energy that the person acquires while ascending the stairs.
work = potential energy acquired = mgh
W = 75kg * 9.8m/s² * 2.50m = 1837.5 J</span>
Answer: yes.
Explanation: The type of light striking the metal is visible light.
There are three factors involved:
1. The temperature
2. The specific heat of the metal
3. The thermal conductivity of the metal.
The increase in temperature of the metal is influenced by how light energy is absorbed and reflected; it will absorb some of the energy and won't reflect all of it.
When an object absorbs visible light, it transforms the short wavelength light into longer wavelength heat, leading to a temperature rise.
